What does high latency mean in this case? I've been in mobile for 15 years and now find myself using S3 as a document backup space. I'm rather alarmed because I'm only seeing, idk, 200-400 ms of latency. But then again, I'm in Boston. Am I just lucky to be near US-East?
- trillic 3y ago200ms is enough for an RTT from Boston-Auckland-Boston. S3 is slow. You’re single digit milliseconds from us-east-1 under optimal conditions.
- Terretta 3y agoYep, using a ping history: Boston - DC shows about 13ms: https://wondernetwork.com/pings/Washington/Boston https://wondernetwork.com/pings/Washington/Boston Boston - Auckland shows about 207ms: https://wondernetwork.com/pings/Washington/Auckland https://wondernetwork.com/pings/Washington/Auckland From anywhere, S3 used to (10+ yrs ago) seem slow enough for a person to feel a delay, 400ms - 800ms plus RTT ping time, but people did and are seeing results sub-200ms perception threshold, i.e., "Average latency per file was 72.3ms" -- but some requests still take a literal second: https://github.com/opendatacube/benchmark-rio-s3/blob/master/report.md https://github.com/opendatacube/benchmark-rio-s3/blob/master... Even a 15 years ago, though, people were seeing sub-100ms to S3: https://www.quora.com/What-are-typical-latencies-for-static-content-in-S3-vs-Cloudfront https://www.quora.com/What-are-typical-latencies-for-static-...
- isignal 3y agoFor a key value store you expect server side latencies less than 5 ms for point gets and writes.
- refulgentis 3y agoThank you!! Exactly what I was curious about: not "is 200 ms slow relative to some other time?" but "_why_ is 200 ms slow?"
